This is going to be the Nerf Fire-er for my auto turret. Couple of mistakes I am too lazy to fix, the center post on the bullet holder needs a horizontal edge filed off it and the firing pad needs to be filed on the side to fit the slide chamber better, so it moves better. Depending on your printer's accuracy you may have to file here and there to smooth things out. Look at projectsentrygun.org for incredibly valuable stuff. Print the pulleys solid for the extra rotational mass. You can figure out parts orientation and supports yourselves, I'm sure.
